One set of rules
SS7 and SMPP suppliers combined in the same routing rules and supplier groups.
Add-on
Auvia SS7: SMPP to SS7 over SIGTRAN
A messaging-grade signalling gateway that converts between SMPP and SS7, for SMS termination, inbound traffic and HLR lookups over SIGTRAN networks. Combined with Auvia Gateway, SS7 and SMPP suppliers share the same routing, pricing and records.

Features
Everything in the Auvia SS7 add-on
53 functions in 10 areas.
Gateway core
SMPP and SS7 in one gateway.
- Protocol conversion between SMPP and SS7 over SIGTRAN (M3UA)
- Connect existing SMSC gateways over SMPP or HTTP(S)
- Connect to mobile operators, MVNOs and signalling carriers over SIGTRAN
- Multiple signalling point codes, SIGTRAN links and SMPP connections
- GSM 7-bit (03.38), UCS-2 and binary SMS
- HLR queries over SS7, also through the HTTP(S) API
- Redundant architecture with scalable throughput
Outbound MT termination
Delivering SMS to any network via MAP.
- Standard MAP flow: SRI-SM for routing information, then MT-ForwardSM
- Configurable timeouts for SRI-SM and MT-ForwardSM
- Validity period of incoming SMPP messages checked before delivery
- SS7 profiles: delivery method, address types, receipt request, data coding, SMSC address, point codes, translation types and extension data
- SS7 errors mapped into SMPP error codes towards the customer
- A transaction record for every outbound MT
Inbound MO reception
A virtual SMSC for mobile-originated traffic.
- Virtual SMSC (vSMSC)
- Reception of MAP MO-ForwardSM
- Allow-list of authorised SMSC global titles
- Validity period check on received messages
- MO delivered to a specific SMPP account
- A transaction record for every inbound MO
Inbound MT reception
A virtual HLR and MSC/VLR for terminating traffic.
- Virtual HLR (vHLR) and virtual MSC/VLR
- Operator database for each MNO and MVNO
- IMSI construction for routing responses
- Inbound MT delivered to a specific SMPP account
- A transaction record for every inbound MT
Signalling routing
Which link carries which traffic.
- Fixed routing: an SMPP trunk bound to a SIGTRAN connection
- TLV-based routing: choose the signalling carrier with SMPP TLV values
- Load balancing across several signalling links
- SS7 profile chosen per routing rule: one connection, several profiles
- Dedicated SS7 supplier prices and simulation in the Routing Analyser
Retry management
Retries built around SS7 error codes.
- Fully configurable retry profiles
- Custom error categories: permanent or temporary
- Retry logic per error code, up to 100 attempts
- Validity period checked for every message waiting to be retried
SS7 firewall and anti-spoofing
Protection of the signalling layer and MO traffic.
- Real-time MO spoofing detection with an SRI-SM verification
- Check on one signalling link or on all links
- Choice of the links used to send the verification
- Optional cache of verification results
- Configurable MAP error returned on spoofing
- Allow-lists and block-lists at SCCP, TCAP, MAP and SMS TPDU level, with combined rules
- Records and live monitoring of every check
Records and traces
Evidence for billing and troubleshooting.
- A record for every SS7 transaction
- Optional delivery of records over SFTP, split by size or time
- Continuous capture of SS7 traffic in PCAP files
- Optional delivery of PCAP files over SFTP
SS7 monitoring
A live view of signalling performance.
- Dashboards of the whole gateway, with custom views
- Transactions per second for outbound MT, inbound MT and inbound MO
- Real-time status of SMPP and SIGTRAN connections
- Traffic status per service and status of number lookups
- SS7 console for test submissions and previews
Signalling onboarding
From global titles to live links.
- Global title implementation
- Provisioning of new signalling links on request
- Monitoring of customers' signalling links
- Troubleshooting support for signalling issues
FAQ
Auvia SS7 questions
What is Auvia SS7?
An add-on to Auvia Gateway: a messaging-grade signalling gateway that converts between SMPP and SS7 over SIGTRAN (M3UA), for SMS termination, inbound traffic and HLR lookups.
Can SS7 and SMPP suppliers be used together?
Yes. SS7 and SMPP suppliers sit in the same routing rules and supplier groups, with separate supplier prices for SS7, and the Routing Analyser simulates SS7 routes too.
Which MAP operations are used for termination?
The standard flow: SRI-SM to obtain routing information, then MT-ForwardSM to deliver, with configurable timeouts for both.
How is MO spoofing detected?
With a real-time SRI-SM verification on one or all signalling links, an optional cache of results and a configurable MAP error when spoofing is found.
Do you help with global titles and links?
Yes. Signalling onboarding covers global title implementation, provisioning of new links on request, monitoring of your links and troubleshooting.
